在风沙治理和沙区植被恢复过程中,沙障设置是项关键技术。针对腾格里沙漠南缘特殊的地理环境,通过设置草方格、黏土方格和尼龙网沙障对比分析不同沙障对植物的保护效果。结果表明,9种不同规格的沙障中,草方格沙障成本低、使用寿命长；不同坡度沙丘,沙障方格大小影响植被成活率与覆盖度,>50°的沙丘上,适宜设置1.5 m×1.5 m 大小的沙障方格。

In the process of the sand control & sand vegetation restoration,setting sand barrier is a kind of key tech-nology.Aiming the special geographical environment in southern edge of the Tengger Desert,protective effect of different sand barrier on plant was analyzed by setting grass grid,clay squares and nylon net.Result shows that a-mong nine different specifications of the sand barrier,straw checkerboard barriers have the characteristics of low cost and long service life;dunes with different slopes,grid size of sand barrier affect the survival rate & coverage of vegetation.The sand barrier grid with the size of 1.5 m × 1.5 m was suitably set on the dunes which were greater than 50°.
